Products
SpheroCompact®
Radius measurement in production
The SpheroCompact® allows radius measurements in production with accuracies of up to ±0.05 %.
- Multi-purpose use, particularly for highly curved convex and concave surfaces because small radii of up to +2.5 mm and -4 mm especially can be measured
- Its compact design allows SpheroCompact® to be used flexibly
- Spherometer optimized with regard to price and performance for use in manufacturing
SuperSpherotronic® HR
Precise and reproduceable
The SuperSpherotronic® HR offers excellent accuracies of up to ±0.01 %.
- Radius measurement of convex and concave surfaces up to +3 mm and -6 mm
- Excellent precision for the measurement of highly curved surfaces with a large lens diameter by means of an increased travel of 60 mm
- Extreme resistance to mechanical deformation thanks to the use of tungsten carbide balls in the ring
UltraSpherotronic®
Highest precision
With an accuracy of up to ±0.005 % the UltraSpherotronic® reaches the highest measurement precision worldwide.
- Radius measurement of convex and concave surfaces up to +3 mm and -6 mm
- Excellent precision for the measurement of highly curved surfaces with a large lens diameter by means of an increased travel of 60 mm
- Extreme resistance to mechanical deformation thanks to the use of tungsten carbide balls in the ring
Software
SpheroPRO
The user-oriented software SpheroPRO was designed to fully meet the requirements in real-life applications. The intuitive user menu permits the easy, quick and error-free determination of the radius of curvature of lenses via pre-configured measurement programs. The current test step can be controlled directly by a schematic representation of the measured radius of curvature (concave or convex). Quality control is performed by means of a continuous statistical analysis of values.
- Very easy handling through pre-configured measurement programs for various applications, e.g.: test tube and single surface measurements
- Fast check of test step and measurement process for plausibility through schematic representaiton of radius of curvature (convex/concave) and current number of measurements
- Continuous quality control through statistical analysis of measurements, including mean value, standard deviations and pass/fail analysis
- Intuitive storage and recall of measurement series for quality control
- Compact but comprehensive documentation in measurement certificates that can be stored digitally and printed
- Intuitive storage of templates (selected ring, nominal radius, selected tolerance)
- Ring calibration data are easy to import and, if necessary, update for product extensions or product checks
- To reduce general maintenance and space requirements, the software has also been designed for touch screen operation. This eliminates the need for a keyboard and mouse
